DD has outgrown her's.
She won't let me measure her (and I'm not really sure how to anyway) but we need new ones. Obviously we can't get her measured because of bl**dy covid restrictions, she can't try them on and I'm not sure what on earth to do.
The only thing I can think is to go out buy a variety and return the ones that don't fit but I'm not sure shops take underwear back and they're not exactly cheap.
Any ideas welcome please?
